Chapter 1 About the Radio Switch RS4000 The Meru Networks Radio Switch RS4000 enables high-capacity enterprise-class wireless LAN connectivity with full support of standard 802.11 security and network management features. Each RS4000 contains four built-in 802.11a/bg radios for high data and voice throughput – an essential requirement for high user-density environments with several simultaneous users. Classrooms and convention halls are typical deployment applications of the Radio Switch.
Figure 1: Meru Radio Switch RS4000 Hardware Features and Specifications Meru’s Radio Switch, RS4000 contains four 802.11 (two 802.11a and two 802.11bg) radios that can transmit and receive simultaneously on four different channels to increase the total available wireless bandwidth at a given area. The RS4000 must be connected to the LAN using one or two 10/100 Mbps Ethernet connections and can also be powered over Ethernet—using two IEEE 802.3af POE connections, with 15W power on each connector.
The RS4000 works in conjunction with an external wideband RF combination omni directional (WRC/OD) antenna. Only one antenna is needed for simultaneous operation of all radios of an RS4000 in both the 2.4GHz and 5GHz bands. The antenna must be connected to the Radio Switch using any one of the low-loss antenna cables provided in the antenna packaging. The RS4000 is a blade-server-type modular design for field-upgrades. By replacing the radio blade inside the RS4000, a higher number of 802.
WLAN Features and Specifications z 802.11a and 802.11b/g client connectivity z Four ESSIDs and four BSSID support z L2 Security — WEP-64 and WEP-128 — 802.
Chapter 2 Installing the RS4000 This chapter describes how to physically install the Meru RS4000.
Planning the Installation z RS4000 Release Notes Safety Precautions Follow the guidelines in this section to ensure proper operation and safe use of the Radio Switch. FCC Safety Compliance Statement The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment.
Planning the Installation Installation Guidelines The RS4000 requires a location that meets the following: z A location to mount the antenna within 3’ of the RS4000 and with relatively unobstructed access to the client stations z Power over Ethernet (PoE) connection to the network switch servicing the RS4000. The RS4000 obtains power from 802.3af standard Power over Ethernet (PoE) compatible network switch or PoE power injector installed between the switch and the RS4000.
Planning the Installation You need the tools listed in Table 2.
Performing the Installation Performing the Installation Installation Summary The summary of the steps to install the RS4000 are as follows: z Initial Configuration of the RS4000 z Wall Mounting the RS4000 or z Hoffman Enclosure RS4000 Installation z Power On Components z Checking LED Activity Initial Configuration of the RS4000 Before the RS4000 is installed in its permanent location, perform an initial RS4000 configuration to assign its IP addressing.
Performing the Installation Once the password is changed, it takes effect immediately (usually the command activate-conf must be used to activate a change). However, the password is active only for the current session. To save the password so it remains in affect after a reboot, it must followed with the commands activate-conf and save-conf. Note: The system checks for passwords that are too simple or similar.
Performing the Installation Activating and Saving Changes After making your configuration changes, it is necessary to activate them using the command activate-conf. Changes are then propagated and started on all radios and will continue running until the system is rebooted. To make sure changes are retained after a system reboot, you must save the active (running) configuration to a startup configuration file, using the command save-conf.
Performing the Installation 2. Choose the location on the wall where the RS4000 will be mounted. The RS4000 can be oriented in any direction, but it is probably more convenient if the SMA antenna mounts are at the top. This orientation is more convenient for reading LED status. 3. Using the bracket holes as a template, mark the location on the wall for the two RS4000 bracket mounting screws. They are placed 5 25/32" (147mm) apart, center-to-center, one above the other.
Performing the Installation 7. Mount the bracket on the screws, placing the circular portion of the keyhole mounts over the screw heads and sliding the bracket down. 8. Tighten the screws to secure the bracket. 9. On the RS4000, attach the two antenna cables to the SMA antenna connectors labeled ANT 1 and ANT 2 on the top panel of the RS4000 (see Figure 4) by turning the cable ends clockwise until tight. 10.
Performing the Installation 4. Attach the top of the antenna to the 1/4-20 threaded stud on the swivel head and tighten the nut against the antenna. 5. Loosen the set screw on the swivel assembly, if necessary, with the Allen wrench that is provided. 6. Position the antenna to maximize the reception and tighten the set screw. Hoffman Enclosure RS4000 Installation Use the procedures in this section to mount the RS4000 within the Hoffman enclosure.
Performing the Installation 5V DC ETH 1 and ETH 2 ETH 1 ANT 1 ETH 2 ANT 2 ANT 1 and ANT 2 Figure 4: RS4000 Top Panel 4. Attach two Ethernet cables to the Ethernet ports labeled ETH 1 and ETH 2 on the top panel of the RS4000. 5. Place the RS4000 into the Hoffman enclosure, and align the plate screwholes with the holes in the Hoffman enclosure. 6. Pass the Ethernet and antenna cables out of the Hoffman enclosure through the cable pass-through holes, if necessary. 7.
Performing the Installation Checking LED Activity Radio switch status LEDs are provided on the face of the RS4000. RS4000 Status LEDs Status LEDs on the face of the RS4000 light, as shown in Figure 5. . POWER RADIO I RADIO II ETHERNET Figure 5: RS4000 Status LEDs The RS4000 uses 4 LEDs.

Chapter 3 Configuring the Meru RS4000 The configuration of the RS4000 includes the following procedures: z Determine How the RS4000 Is To Be Managed z Configuring of the Radio Switch with the CLI Commands z Activating and Saving Changes Determine How the RS4000 Is To Be Managed The RS4000 can be managed remotely with third-party SNMP Manager software or directly with the CLI via a Telnet or SSH connection.
Determine How the RS4000 Is To Be Managed Caution! As shipped, the system is set with a default password and default SNMP community strings that allow documented access to the management interfaces. It is strongly recommended that you change these default settings as soon as possible to prevent unauthorized access to your system. The commands to perform these changes follow.
Configuring of the Radio Switch with the CLI Commands # set snmpcommunity RWManagerIpAddress 192.168.300.100 To allow all SNMP managers in the network to have read/write access, do not use the command set snmpcommunity ROManagerIpAddress. Instead, the default IP address setting 0.0.0.0 is used to allow all SNMP managers with the community string CatsCradle to get/set MIB objects. Note: If need be, the default IP address can be reset by using the 0.0.0.
Configuring of the Radio Switch with the CLI Commands [radio1-1] status = up essid = meru1-1 mode = 11a channel = 36 rate = auto tx_power = 30 rts_threshold = 2312 dtim_period = 1 publish_ssid = enable beacon_interval = 100 vlan_tag = 0 [radio2-1] status = up essid = meru2-1 mode = 11g channel = 1 rate = auto tx_power = 30 rts_threshold = 2312 short_preamble = enable dtim_period = 1 publish_ssid = enable beacon_interval = 100 vlan_tag = 0 [radio1-2] status = up essid = meru1-2 mode = 11a channel = 149 rate
Configuring of the Radio Switch with the CLI Commands security_mode = none wep_security_mode = shared wep_key_len = wep64 tx_key_idx = 1 rekey_period = 300 reauth_period = 3600 [wifsec_radio2-1] security_mode = none wep_security_mode = shared wep_key_len = wep64 tx_key_idx = 1 rekey_period = 300 reauth_period = 3600 [wifsec_radio1-2] security_mode = none wep_security_mode = shared wep_key_len = wep64 tx_key_idx = 1 rekey_period = 300 reauth_period = 3600 [wifsec_radio2-2] security_mode = none wep_security_
Configuring of the Radio Switch with the CLI Commands upasswd = admin Configuring an ESSID The RS4000 allows each of the interfaces to have a separate ESSID. By default, meru1-1 is specified for radio1-1 and meru1-2 for radio1-2; meru2-1 is specified for radio2-1 and meru2-2 for radio2-2.
Activating and Saving Changes For 802.11bg radios: z Channel 1 and Channel 11 For 802.11a radios, use any of the following combinations: z Channel 36 and Channel 48 z Channel 40 and Channel 52 z Channel 44 and Channel 56 z Channel 48 and Channel 60 z Channel 52 and Channel 64 # # # # set set set set wif wif wif wif radio1-1 radio1-2 radio2-1 radio2-2 channel channel channel channel 36 48 1 11 The following commands set rates for 802.11bg interfaces and 802.
